M51 Whirlpool Galaxy
M51 Whirlpool Galaxy
This is a grand design spiral galaxy with an interacting neighbor being tugged into it’s spiral arms (NGC 5195). M51 never sets for me in the northern hemisphere, making this circumpolar target fun to image with it’s bright arms and hostile takeover of it’s smaller buddy.
